Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face issues with conductive terminals becoming denser, leading to assembly misalignment, tilting, and potential short circuits due to increased pressure, which can damage the terminals and result in excessive pressing by the chip module.
Innovation Solution
The electrical connector features supporting portions with guide portions on the insulating body to prevent excessive pressure and align conductive terminals, ensuring proper contact and preventing short circuits by guiding the extending arms back to their correct positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the size of the electrical connector becomes smaller and conductive terminals become denser, then the compactness of the connector is improved, but the assembly precision and reliability deteriorate due to misalignment, tilting, and potential short circuits between adjacent terminals
Solution Approach 1:
The patent applies preliminary action by providing guide portions on the insulating body before the conductive terminals are assembled. These guide portions pre-establish the correct positional relationship and alignment for the terminals, ensuring that even when terminals are densely packed, they can be accurately positioned during assembly. This preliminary guidance structure prevents misalignment and tilting that would otherwise occur in compact designs.
Solution Approach 2:
The guide portions act as an intermediary element between the insulating body and the conductive terminals. This intermediary structure facilitates proper alignment and positioning of the terminals during assembly, mediating the interaction between the dense terminal arrangement and the insulating body to prevent short circuits while maintaining compact dimensions.
2Reliability
If supporting portions are provided to prevent excessive pressing of elastic arms, then the reliability of the connector is improved, but the harmful effect of elastic arms scraping and damaging conductive terminals occurs
Solution Approach 1:
The patent extracts the harmful scraping function from the supporting portions by removing or modifying the portions that come into contact with the elastic arms. The guide portions are designed to provide support and alignment without creating scraping contact with the moving elastic arms, thus taking out the harmful factor while retaining the protective support function.
Solution Approach 2:
The patent applies local quality by differentiating the functions of different portions of the support structure. The guide portions provide alignment and support with smooth surfaces that do not scrape, while other portions may have different characteristics. This localized differentiation ensures that support is provided without the harmful scraping effect on the elastic arms and terminals.
3Reliability
If the elastic arms are made more elastic to ensure better contact with contact pads, then the electrical conductivity is improved, but the susceptibility to deflection and short circuiting increases under pressure
Solution Approach 1:
The patent applies the counterweight principle by providing guide portions that counteract the deflection tendency of the elastic arms. When elastic arms are pressed and tend to deflect, the guide portions provide a counterbalancing alignment force that pushes them back into the correct position, preventing short circuits while allowing the arms to maintain their elasticity for good electrical contact.

AI summary
An electrical connector is electrically connected to a chip module having multiple contact pads. The electrical connector includes an insulating body having multiple accommodating grooves. Multiple conductive terminals are respectively accommodated in the accommodating grooves. Each conductive terminal has a main body portion accommodated in a corresponding accommodating groove and an extending arm extending forward from an upper end of the main body portion. Each extending arm of the conductive terminals is used to be upward electrically connected to a corresponding contact pad. At least one supporting portion is provided on the insulating body and located at one side of a corresponding accommodating groove. A first guide portion protrudes and extends from a top end of the supporting portion to upward abut the chip module. A horizontal projection of the extending arm of at least one conductive terminal partially overlaps with a horizontal projection of the first guide portion.
